Securing the Switch for Cisco CCNA 200-125/100-105
Switch security is where most CCNA candidates stumble—and where employers expect competence. This focused course drills the switching and security fundamentals that appear across both 200-125 and 100-105 exam blueprints, with live lab scenarios you’ll actually encounter in production networks.
AIU.ac Verdict: Ideal for CCNA candidates who need targeted switch security depth without the fluff, or junior network engineers bridging knowledge gaps before certification. The 2h 25m runtime is lean, so you’ll need supplementary study materials if you’re starting from zero networking experience.
What This Course Covers
The course tackles VLAN configuration, trunk protocols, port security, and access control lists (ACLs) as they apply to switch infrastructure. You’ll work through real scenarios: securing unused ports, preventing MAC flooding, configuring port-based authentication, and implementing layer 2 security best practices that align directly with exam objectives.
Expect hands-on labs in Pluralsight’s sandbox environment where you configure switches, test security policies, and troubleshoot common misconfigurations. The content bridges both exam versions (200-125 and 100-105), so you’re covered regardless of which path your employer or certification timeline demands.
Who Is This Course For?
Ideal for:
- CCNA exam candidates: Sitting 200-125 or 100-105 and need focused reinforcement on switching and layer 2 security topics before test day.
- Junior network engineers: Recently hired into support or operations roles and need to close knowledge gaps on switch hardening and VLAN security without lengthy courses.
- Career switchers into networking: Coming from IT support or systems admin backgrounds and want targeted, practical switch security skills before pursuing CCNA formally.
May not suit:
- Complete networking beginners: No prior exposure to OSI layers, IP addressing, or network topologies—you’ll struggle without foundational context.
- Advanced network architects: Already CCNP-level or designing enterprise security—this course won’t add value; it’s exam-prep, not architectural depth.
